|
|
Pressure is....
|
force per unit area
|
|
|
What are four physical properties of gases?
|
Always fill their containers
Are highly compressible Diffuse Temperature effects either the volume or the pressure of a gas |
|
|
The pressure exerted by air
|
Atmospheric pressure (1 atm)
|
|
|
________ effects either the volume or pressure of a gas
|
Temperature
|
|
|
Gases increase in volume and pressure when _______
|
Heated
|
|
|
At sea level, average atmospheric pressure is about....
|
101 KPa
|
|
|
What does STP stand for?
|
Standard temperature and pressure
|
|
|
What does SATP stand for?
|
Standard ambient temperature and pressure
|
|
|
What is Boyle's Law?
|
as the pressure on a gas increases, the volume of the gas decreases, other variables such as temperature and amount of gas remain constant.
|
|
|
How can we write out Boyle's Law?
|
V1P1= V2P2
|
|
|
Convert 20 degrees celcius into Kelvin
|
293 K
|
|
|
Convert 300K into degrees celcius
|
27 degrees celsius
|
|
|
What are the temperatures in K of STP and SATP?
|
STP= 273 K
SATP=298 K |
|
|
French physicist Jacques Charles determined the relationship between the ______ and ______ of a gas
|
temperature and volume
|
|
|
What number do you add to convert degrees celsius to kelvin?
|
273!!
|
|
|
What does the Charles law state?
|
The volume (V) increases proportionally as the temperature (T) increases
|
|
|
What is the formula used in the Charles Law?
|
V1 = V2
-- -- T1 = T2 |
|
|
True or false
Temperature must be in Kelvin in the Charles Law? |
True
|
|
|
What do you call the Charles and Boyles Law when put together?
|
The combined gas law
|
|
|
What is the formula for the combined gas law?
|
p1v1 = p2v2
------------ T1 T2 |
|
|
Molar mass is in...
|
g/mol
|
|
|
How do we calculate the molar mass?
|
1. Write the correct chemical formula
2.Find the atomic molar mass 3. Add together |
|
|
What formula do we use when we need to find the relationship of amount in moles, mass and molar mass?
|
n= m
-- M |
|
|
What is the molar volume of a gas at SATP?
|
24.8 L/Mol
|
|
|
What is the molar volume of a gas at STP?
|
22.4 L/Mol
|
|
|
Why is it easier to work with volume instead of the mass of a gas?
|
It is much more convenient because it is more precise, since gases have such small amoounts of mass.
|
|
|
what is the formula for molar volume?
|
n= v
--- V |
